Docket Nos. 50-413 and 50-414 Tecluti* cal Specification Amendment for Dissel Generators

'.s'

Dear )fr. Dsnton:

This letter is to' clarify some of clie Techtilcal Specification changes requested in my. letter of March 24, 1986.

c..

.The March 24,1986* request inadvertently omitted the appropriate Action ' stat ' ment..

for..the' condition where only one diesel is inoperable. This clarification adds the

. neces'sary requirement on page. 3/4 841. Also, tiie words "(if applicable)" are tb be added to clarify that Action b. may not be applicable if both offs'ite circuits are operable while one diesel is inoperable.

~

_ On page 3/4 8-2, Action statement d., the words " separately for each diesel' generator" are to be added to clarify the intent of the required action when both offsite A'C.' circuits are ingperable.

~

The final change is on page 3/4 8-7,, Stirveillance 4.8.1.1.3 which retains the la' t s

sent9nce in the Surve,illance.

The previous submittal had 's equested that this1 sentence be deleted as was done in the North Anna Specifications. Basedujon' conversations with your staff, this sentence is to remain.

o

~

Ps s ant to 10 CFR 50.91 (b) (1) the appropriate South Carolina State Official is being provided a copy of this. clarification to our amendment requeet.-

~

Ve'ry truly you,rg,.,
